the J20 is a fairly heavy rig. It also depends on what you want to do with it and what size tire you are going to run on it. I would think at least a 35 and you would be pushing the limits of the 44. if there is any kind of rocks involved I would think 60/60.. or even a 60/70 does it already have the 44/60? if so run it till it breaks.

...but what do i know, i run a sami

It;s a pretty common selection. I ran a 9" rear and a 44 front. (Also a 44 R/44F) also a 8.25R/30F, currently 9's F&R)

As to the effort, need more info. Spring under axles, Spring Over axles. Your vehicle is SUA, SOA, Coils now?

Recommendations: Depends on tire size, will you have a selectable front locker, is it a trailer queen, or a Daily Driver? Stuff like that.

But overall, 60R 44F is pretty common and good through 35's to 37's depending how hard you plan on being on the front axle.

sorry, i would pull the axles and put them under my xj

i was thinking about using the tnt truss (since it has everything already in place) and the rear is still leaf sprung, im not scared of welding perches.

from what im reading, people say there are wide (i understand)... but ive also read the 60 is weak? idk... lol...

Derik hit all the key points.

Need to know more before can really say.
Is it going back in a J20 or are you putting it in a CJ-5. Hugh differances.

But over all it's a common reliable setup. depending on your driving style plan on upgrading both to Chromolly shafts and if you are going to be changing the gears go ahead and upgrade to a larger shaft which requires a carrier change.
Example. Stock dana 60's use a 30 spline shaft. Only a little larger than a dana 44. But it can be upgraded easily to a 35 spline shaft which will hold up to 38's no problem.

With these axles in stock form you are looking at the 35 to 38" tire range depending on which shafts/ u-joints/ gears/ weight of rig/ weight of tires/ etc and how you drive.

If you ever plan on going larger than 38" tires hold off for something stronger in the front. Dana 60, Ford 9, (609), corp 14, Rockwell, or tracter axle.

Sounds like you got the rear figured.
The front isn't all that hard to convert to a 4 link. Buying some stronger axle brackets for the control arms would be the best. locating them is just an exercise in math.

The track bar is pretty straight forward as well. I would recommend an other the axle track bar bracket. JKS, Rustys ets. This puts the track bar higher in the axle plane, freeing up room for the tie rod/drag link and/or for a ram in the future. Does require changing the length of the track bar and maybe the axle end as well. But a really good mod to make.

The sway bars will need to be redone as well. You could take the axle mounts from the D30.

A word of warning, if it's out of a Quadratrac J20, the rear diff will be offset to the pass side.

I think the answer is no. But you would have to take measurements to measurements to make sure. Distance from center section to inner C and Inner C to Inner C are the one's that I would think critical.

I have a Waggy 44 if you want to compare.

I like the Tnt truss. I just sold one a few months ago.
Just a note. They are easy to place but still require a fair amount of welding.
